ORLANDO, Fla., Dec. 12, 2012 (GLOBE NEWSWIRE) -- Cleantech engine supplier Power Solutions International, Inc. ("PSI") (OTCBB:PSIX) is showcasing its expanded engine lineup at the 2012 POWER-GEN International Trade Show, December 11—13 in Orlando. The company is presenting power systems from .97-liter to 21.9-liter, including three engines that can now achieve industry-first power outputs: the .97-liter turbo, the 5.7-liter turbo charge air-cooled, and the 8.8-liter, available in four new options.

"These engines are just what industrial OEMs are looking for—compact, cost-effective power solutions," said Eric Cohen, Chief Operating Officer of PSI. "Our new systems provide greater outputs in smaller packages at a lower cost per kilowatt."

PSI is displaying four industrial engines—the .97-liter, 3.0-liter, 5.7-liter and 8.8-liter—as well as four engines from the PSI Heavy-Duty line: the 11.1-liter, 14.6-liter, 18.3-liter and 21.9-liter. The new .97-liter, 5.7-liter and 8.8-liter engines are notable for providing unprecedented power for their respective displacements.

The all-new .97-liter turbo is a 4-cylinder, electronic fuel-injected gas engine that produces nearly 25% more power and torque than the naturally aspirated version reaching 25 kWe. PSI introduced the .97-liter turbo at the 2012 Golf Industry Show powering John Deere's Gator Utility Vehicles. The new emission certified stationary model featured at POWER-GEN provides diesel-level power, performance, durability, and reduced noise, vibration and harshness through features including a closed-loop port-injected EFI, a cross-flow cylinder head to optimize fuel combustion, high silicon content pistons, sintered powder-metal exhaust, valve seat inserts and a poly V-belt harmonic balancer.

The all-new 5.7-liter turbo/gearbox/charge air-cooled engine is capable of producing 130 kWe of power. The system offers OEMs a durable, cost-effective alternative to the Ford 6.8-liter engine.

PSI's big block 8.8-liter engine, first introduced in 2011, is now available in four new options capable of producing 100—180 kWe: naturally aspirated, turbo-charged, and two charge air-cooled versions. The newly designed and engineered engine offers 20% across-the-board improvements in power and 15% better fuel-efficiency than its predecessor, the General Motors 8.1L.

The PSI Heavy-Duty line features heavy-duty engines with expanded outputs spanning from 80 kWe to 430 kWe. The fuel-flexible Heavy-Duty engines range includes 8.1-liter to 21.9-liter blocks designed to deliver performance and reliability for demanding applications.

PSI is showing its expanded engine lineup in booth number 2006 at the 2012 POWER-GEN International Trade Show, taking place December 11—13 at the Orange County Convention Center in Orlando, FL.
